Public bug reported:
Netplan is not correctly creating configuration for ethernet card.
Instalation of Ubuntu created file /etc/netplan/00-installer-config.yaml wiht
dhcp configuration.
After the first login from GUI was created configuration with static ip4
address.
The final configuration in
/run/NetworkManager/system-configuration/netplan-enp2s0.nmconnection contains
both: address and dhcp (auto). When interface is activated it is after a few
seconds disabled.
